Washing machine shakes like crazy during spin cycle! How can I fix it? :[

So we bought new washing machines, and the dryer works perfect! But, the washer for some reason during the spin cycle shakes like crazy! Very violently, and we can't seem to stop it.

We tried screwing it onto the bottom drawer, and what happened was it just shook and shook until it undid the screwing.

Has anyone ever had a machine do this? And how did you fix it?
